Most likely it's not semget() but earlier in the initial IPC setup in
CreateSharedMemoryAndSemaphores() with parallel connections.
I always get IsBadWritePtr() in shminit() since 8.0-beta3.
Just tested again (make check MAX_CONNECTIONS=5) and again got:
creating template1 database in 
/usr/src/postgresql/postgresql-8.0.3/src/test/regress/./tmp_check/data/base/1 
... Signal 12
"child process exited with exit code 140"
